shot clock reset?

[Nevadaref]

I posted this on another thread, but didn't get much of a response and I would really appreciate one. So...
For the purpose of resetting the shot clock, is it considered a shot if the player never lets go of the ball?

For example, a player attempting a dunk, pins the ball against the rim and then comes back down with it.

Or what about a player who simply jumps and touches the ball to the rim and then returns to the floor?
